4.0 Tag Unwind Brake
A spring-loaded dancing arm and rubber friction brake band are
used to control the tag supply.
Figure 6–1 Supply Reel Brake for Inside-wound Tags
Each month, check for wear of the rubber friction brake band. If the
brake band or the springs are showing signs of wear, or the brake is
not operating correctly, the brake band should be replaced.
If the brake is not operating correctly, a heavy supply reel will tend to
overrun and introduce slack into the tag supply path.
To replace the brake band:
• Power off the machine
• Turn and lock off the air supply
• Remove the tags from the machine
• Loosen, but do not remove, the two grub screws in the inner
locking ring
• Remove the inner locking ring and the inner Perspex disk
• Unscrew the screws that secure the brake band to the dancing
arm and base plate and fit the new band
